can you put a comment saying that this is only needed for the bb_js hack

Description
Problem*
Resolves #1489
Summary*
The relevant ACVM rev that is updated to in this PR:
noir-lang/acvm#291
The updated acvm-backend-barretenberg:
noir-lang/acvm-backend-barretenberg#207
This PR sets out to enable compilation of ACIR circuits and witness generation in a format the
bb.jsexpects. nargo built with thebb_jsfeature flag should only use thecompileandexecutecommands as the rest are unimplemented. Untilbb.jsis fully integrated to nargo and/or fully dynamic backends are ready the other commands will not be usable withbb.js. This is an experimental feature and should only be used by advanced users comfortable with downloading from source and escaping from the normalnargoworkflow.Example
Before:
You could call
cargo install --path=crates/nargo_clito use nargo with the nativeacvm-backend-barretenberg. Addtional flags of--no-default-features --features=plonk_bn254_wasmwould enable compilation with a wasm target.Users can then use nargo commands to not only compile, but prove and verify their circuits such as with
nargo prove p --verify.After:
The previous commands work the same as before. However, adding the flags
--no-default-features --features=bb_jswill let a user compile a Noir circuit and generate a witness to file in the format thatbb.jsexpects. However, proving and verifying will be done withbb.js. Binaries are being released forbb.js. Once someone hasbb.jsinstalled globally they can use it according to its CLI.To prove and verify w/
bb.jsthe following command can be run over a compiled circuit and witness:bb.js prove_and_verify -j ./target/c.json -w ./target/witness.trDocumentation
This PR requires documentation updates when merged.
